The victims of airbnb and short term rentals

I've heard people say that airbnb and the like are disrupting the hotel industry by letting anyone rent out his or her residence. This may seem like a great idea until you're the person living next door to one of these rentals. Instead of having a neighbor that you know by name, you have random people staying for 1 night, 3 nights, a week. This can bring more crime, noise, and reduce property values. San Francisco just passed an ordinance regulating short term rentals putting a cap on the number of days a place can be rented a year. This number is capped at 90 days, but that is still far too many, in my opinion.

My neighbor decided earlier this year to kick out the family that had been renting his house for a few years and turn it into a vacation rental. He claims that he is a "family man", but the only motivation for doing this is greed. He "fixed up" the house by putting in a hot tub, redoing his deck and planting grass. His vacation rental doesn't fit into our neighborhood as all the houses in the immediate area are single family houses that are either owner occupied or long term rentals (I'll ignore the mini-dorm across the street owned by another greedy person). So now we're going to get random people staying at the house and have to deal with potential noise and the feeling that we may not be safe because we have no idea who is supposed to be next door.

The city of San Diego is too chicken to pass regulations on short term rentals because that would affect beach rentals and other rental properties that bring the city money via the transient occupancy tax (provided people collect and report it). Zoning laws are supposed to separate different uses for properties, i.e. commercial and residential. A short term rental is definitely commercial as a residence is where someone lives. Shouldn't short term rentals fall under commercial zoning regulations?

People could have similar arguments against bed and breakfasts, but they are more regulated (one we stayed in said that they could only serve breakfast and not any other meal) and have a host/manager on site.

The rise of short term rentals anywhere someone wants may be good for the property owners, but in my opinion, is not wanted by many residents of neighborhoods.
